Problems solved by technology

A number of clinical trials on LAA occluders have shown that LAA occlusion is not inferior to warfarin in preventing atrial fibrillation stroke, but due to safety factors such as pericardial effusion and shedding, the US Food and Drug Administration (Food and Drug Administration) and Drug Administration, FDA) is currently only approved for clinical research

Abstract

The invention relates to the field of medical instruments, and discloses a left atrial appendage plugging device which comprises a support skeleton e and a choke membrane; the support skeleton is a hollow near-spherical body having elasticity; the choke membrane is cap-shaped and is arranged on the proximal periphery of the support skeleton; an anchor thorn is arranged on the distal circumference of the support thorn, and is used for grasping on the inner wall of a left atrial appendage. The invention further discloses a left atrial appendage plugging system which comprises a conveying device and the left atrial appendage plugging device mentioned in the technical scheme above; the conveying device comprises a conveying sheath and a push rod; the left atrial appendage plugging device is arranged in the conveying sheath; one end of the push rod is arranged in the conveying sheath, and is detachably connected with the fixed end of the left atrial appendage plugging device. According to the left atrial appendage plugging device and system, the damage to vascular access can be reduced so as to reduce the operation risk.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a left atrial appendage occlusion device and occlusion system for preventing embolism complications of atrial fibrillation. Background technique [0002] Atrial fibrillation (Atrial Fibrillation, AF) is one of the most common clinical arrhythmias. In addition to inducing or aggravating the risk of heart failure, it can also cause stroke and other thromboembolic events, resulting in death or disability. Oral anticoagulant drugs can significantly reduce the probability of ischemic stroke in patients with atrial fibrillation, but because their pharmacological effects are affected by many factors (such as drugs, food, etc.), frequent blood sampling is required to monitor coagulation indicators. Even within the appropriate anticoagulation intensity, it will increase the chance of intracranial hemorrhage by 2 to 5 times. Some patients have contraindications such as active blee...
